Description

Cage type vertical spindle wind-driven power generating prime mover

A kind of full differential cage upright shaft wind power generation driving device belongs to the wind motor technical field, is used for the motive force of wind-driven generator.

Continuous minimizing along with the mineral fuel storage capacity; the appearance of worldwide energy crisis, countries in the world are more and more paid attention to the development and use of solar energy and wind energy in recent years, particularly wind-power electricity generation are paid close attention to more; as California, USA, has only just installed surplus the wind energy power unit 20,000 in state.The kind of wind-driven generator is a lot of at present, but divides by its structure, and be broadly divided into two big classes: a class is a horizontal axis wind-driven generator, and another kind of is vertical-shaft aerogenerator.The former is as motility device with various multi-form propeller blades, carry out the air-flow guiding with the caudal lobe that keeps out the wind, the torque that its blade face wind-engaging power effect produces is little, efficient is low, and lag behind the variation of wind direction during operation because of guiding, add that fan blade, the effect of vertical rod wind-engaging power produce moment of flexure, thereby complete machine oscillation, wearing and tearing and noise all very big, general every use once, 2 years need overhaul; The latter can be divided into two kinds again by its force way: a kind of is the lift formula, and another kind is a differential force type.Lift formula efficient is higher, but detent torque is little, and two, can't start during force 3 wind; The differential force type detent torque is bigger, but efficient is lower.In order fully to develop abundant wind resource, must the new wind-power electricity generation driving device of design.

It is a kind of relatively simple for structure that the purpose of this utility model is to provide, be easy to maintenance service, long service life, the whole advantages that both kept vertical-shaft fan, have big detent torque and high efficiency more again, wind only produces thrust basically to rotor and does not produce the full differential cage upright shaft wind power generation driving device of resistance.

Can form the basic demand of full differential state to rotor according to wind, with the aerodynamics basic principle, at the subject matter that exists in the prior art, basic design of the present utility model is: the air-flow guiding adopts fixing comprehensive formula, promptly manage-style from which direction does not blow, and also changes direction howsoever, and it is poor to make rotor produce maximum thrust, realize promptly " full differential " that this partly main shape, piece number and deflection angle by guide plate is realized; The rotor that directly drives generator is by departing from diameter and form away from the fan blade in axle center with certain orientation with above-mentioned guiding plate number is corresponding, and adopts new design in shape at fan blade; Mode of braking is taked the centrifugal braking of ball formula or additional another generator brake, thereby realizes purpose of design.

Of the present utility modelly be characterised in that described full differential cage upright shaft wind power generation driving device is by gas-flow deflector, barge board, the rotor fan blade, flange plate, propping up that brake member and confession above-mentioned each parts of installation and supporting with it generator are used is configured to, above-mentioned gas-flow deflector by with equivalent in the same way 6～12 guide plates being fixedly mounted on the rotor cylindrical of deflection angle and symmetric arrays form, its effect is that manage-style from which direction does not blow, also change direction howsoever, it is poor to make the rotor of direct drive generator for electricity generation produce maximum thrust, promptly realizes full differential; Above-mentioned barge board is made up of each non-equilateral quadrilateral space thin plate of two ends about being loaded between above-mentioned per two gas-flow deflectors, and each barge board that is positioned at same end is interconnected to a polygonal, works the effect of going for a drive, to increase the thrust to rotor; Above-mentioned rotor fan blade is by departing from diameter in the rotating shaft that is loaded in the rotor cylindrical and away from the axle center and with an angle of lead, with the axle center is the wing fan blades composition of 6～12 rotation variations of center symmetric arrays, existing so bigger torque, good air dynamic behaviour is arranged again, make it that the wind speed to different stage all can produce bigger thrust with the wind the time, and produce minimum " negative pressure " in upwind; Above-mentioned brake member is the centrifugal brake component of bead or additional another generator, and the former utilizes when blower fan reaches certain rotating speed, and bead is centrifugal to be opened; The clutch that closes produces braking action, and the latter drives another generator work by centrifugal contactor when wind-force is big to a certain degree the time again, not only can increase output power but also reach the purpose of deceleration; Totally two of above-mentioned flange plate, fixedly connected with band steel pipe or angle steel that the installation fan blade is used in the two ends that lay respectively at above-mentioned rotor fan blade rotating shaft.The angle of yaw that above-mentioned gas-flow deflector symmetric arrays is installed be the best with 70 °～80 °, because too big air-flow going direction changing is too big, flow velocity can reduce, and flow reduces, too little can generation leaking out, and reduction thrust is poor.The above-mentioned every leaf of rotor fan blade is the oblique rotor blade streamline that cuts away some of its tail end.The angle of lead that fan blade departs from diameter is the best with 40 °～50 °.After above-mentioned each parts and the generator that matches with it (hundreds of watts small generator can be used magneto, general adopt commercially available diesel generator) are installed on the above-mentioned support, small-sized available belt pulley transmission, general used gearbox speed change transmission.

Outstanding advantage of the present utility model is: except that having kept not vibrating of vertical-shaft aerogenerator, noise is little, easy-maintaining, beyond the advantages such as long service life, again because gas-flow deflector of the present utility model can produce the full differential effect, so being compared with similar S type or D type machine, the efficient of wind-power electricity generation can improve 30～50%(if only by fan blade diameter and high computational, efficient can improve more than 200%), because the shape of rotor fan blade, quantity and mounting type are scientific and reasonable, be existing bigger torque, good air dynamic behaviour is arranged again, so make this device wind speed to different stage with the wind the time all can produce bigger thrust, and produce minimum negative pressure in upwind, use this device to utilize wind-power electricity generation just not to be subjected to the restriction of area and wind-force size like this, in addition this device can with the supporting use of multiple generator, applied range.To make the abundant regional resident living power utility wind-forceization of the particularly coastal wind resource of China after the utility model is promoted, thereby realize little investment, and need not establish utility pole, save the energy and electric wire and converting equipment, the ideal that the resident can not hand over or pay tariff less.
